Description

  The present invention is a method for producing a wood-based composite material by manufacturing a wood-based composite material by stacking elongated wood-material pieces mixed with a binder substantially in the length direction to form a wood-laminated mat, and applying pressure or heating with a press molding apparatus. When a mat is placed on a call board and transported while protecting both sides with side guides, the wooden laminated mat is used when the wooden laminated mat is exchanged from the side guide to a stock yard side guide or the like for storing in the stock yard. TECHNICAL FIELD The present invention relates to a side guide that can be exchanged without breaking both side surfaces, a wooden laminated mat conveying device using the side guide, and a wooden laminated mat conveying method.

  As a method for obtaining a wood-based composite material, for example, a fixed-size material in which arrayed lignocellulosic fibers are fixed with an adhesive, and the lignocellulosic fibers are about 6 inches (about 15 cm) to about 4 feet (about 122 cm). ), A width of about 0.05 inch (about 0.1 cm) to about 0.25 inch (about 0.6 cm), and a length of about 0.05 inch (about 0.1 cm) to about 0.5 inch ( A thickness of about 1.3 cm), and the strength of the obtained sizing material is equal to or higher than the strength of at least one grade of lumber cut and sampled from the above-mentioned lignocellulosic fiber There has been proposed the above-mentioned sizing material characterized by having the resin solid content of the adhesive and the density of the obtained sizing material (for example, see Patent Document 1).

  Moreover, it is a plate-like product, the plate-like product has a thickness of 25 mm or more, is cut out from a single-layer panel made of a wood wafer, the wafer is aligned in a certain length direction, When the wafer is measured in the longitudinal direction in the large plane of the single-layer panel, the average deviation with respect to the major axis of the panel is in the range of 0 to 10 degrees, orthogonal to the large plane and in the longitudinal direction of the panel The average deviation when the wafer is measured in the length direction within a small plane is within a range of 0 to 5 degrees, and the wafer has an average length of 200 mm or more when measured in the grain direction of the wafer. The shaped product forms a width portion of the plate-like product by a pair of cut surfaces separated by a predetermined distance, and the cut surface is substantially parallel to the long axis of the single-layer panel from which the plate-like product is cut out. Wafer board plate products are known That (for example, see Patent Document 2.).

  The fixed-dimension material described in Patent Document 1 and the plate-shaped product described in Patent Document 2 are all arranged in the length direction of the cellulose fiber or the elongated wooden wafer along the length direction of the product, and bonded as necessary. It is obtained by mixing the agents and orienting and laminating them in a mat shape, and then applying pressure or heating, and can be applied as a wood-based structural material because of its high strength.

When obtaining a high-strength wood-based structural material such as a fixed-size material as in Patent Document 1 or a plate-like product as in Patent Document 2, an elongated wooden material can be obtained regardless of the shape of the product. A binder is mixed in the piece, and the length direction is aligned so that it becomes a long plate shape with a substantially rectangular cross-section to form a wooden laminated mat. This wooden laminated mat is placed on a call board, and the call board is conveyed. If it is necessary to place it on the equipment, it is transported to the stock yard while protecting both side surfaces with side guides, and it is taken out of the stock yard to measure its weight or moved to a pressurizing / heating press molding equipment. In general, a general method of obtaining a molded body by pressurization or heating is employed.

  However, as described above, the long wooden pieces are arranged along the length direction of the product, and this is pressed to form a product with a desired thickness and laminated into a mat shape. Then, there is a problem that both sides of the wood laminate mat aligned in the length direction tend to collapse as the thickness is increased.

  Normally, when manufacturing a wood-based composite material, it is necessary to transport such a wood laminate mat to a press molding device and transfer it onto the press platen of the press molding device. In order to prevent collapse, side guides are provided over the entire conveyance path. However, when transferring the wood laminate mat in order to place the wood laminate mat aligned in the length direction in the molding die of the press molding apparatus, both sides become more as the thickness of the wood laminate mat increases. There was a problem that it was easy to collapse.

  Furthermore, when manufacturing wood-based composite materials, the wooden laminated mats placed on the call boards are temporarily stored in the stock yard together with the call boards in order to increase the working time of the press molding equipment. Often it is supplied to the machine.

  In the stock yard, if the time required for pressing differs from the time required for orientation, or for convenience in production, temporarily remove the call board from the line, stock it, and return it to the line when necessary. Therefore, it is a facility provided in the middle of the transport line, and is a facility for storing the wood laminate mat before pressing in a state in which the orientation is maintained. For that purpose, the wood laminate mat laminated on the coal board while maintaining the orientation state must always be kept between the coal board and the side guides arranged on the left and right of the wood laminate mat. .

  Moreover, in order to press in the state in which the orientation state in the orientation layering process is maintained, it is necessary to always hold both side surfaces of the wood laminate mat with side guides from the layering process to the stock process and further to the pressing process. . In the stock process, depending on the location of the stock place in the stock yard, the call board is temporarily moved in either the up / down direction, left / right direction, or even diagonal direction of the transfer line, so it can be moved accordingly. It is necessary to use a proper side guide.

  When temporarily storing in the stock yard, the call board on which the wooden laminated mat is placed is inserted under the stock yard side guide disposed at a predetermined position of the stock yard. Therefore, the both side surfaces of the wood laminate mat are replaced with the side guides for the stockyard from the side guides during conveyance.

  The side guide for the stockyard is placed on the call board so as to cover and cover both side surfaces of the wooden laminated mat on the call board inserted therebelow. Accordingly, in this operation, the stockyard side guide is merely placed on the call board and is not fixed, and therefore the position of the call board may be shifted when the call board moves.

  In addition, in such equipment, considering the shift when moving the side guide, the side guide provided on the moving device in the stock yard and the upstream side or the next side guide in the connecting portion It is necessary to provide a clearance of about 2 to 10 mm. However, this clearance causes the chip of the wooden laminated mat to collapse outward from the side guide, or the chip is sandwiched in this clearance, resulting in disordered orientation, body collapse, and cracking of the wooden laminated mat.

  Further, the weight of the wooden laminated mat carried out from the stock yard is measured before being supplied to the press machine. In this work, the insertion device is placed on the weighing device. At this time, the insertion device is raised or lowered by a jack such as an air cylinder. During this lifting operation or during the subsequent transport process, the molding die side frame disposed above the lower pressure platen of the press molding machine. The center line of the wood and the center of the wood laminate mat are displaced. That is, when a call board with a wood laminate mat is inserted into a press panel of a press molding apparatus and placed at a predetermined position, it is between the inner surface of the side frame above the press panel and the inner surface of the side guide of the insertion apparatus. A level difference will occur.

    When the inside of the side guide of the insertion device is inserted into the press mold side frame, the wood laminate mat, the caul board, and the side guide are advanced by the insertion device, and the end surface of the side guide collides with the end surface of the press side frame. And contact. At this time, if the center line of the molding die side frame is shifted from the center line of the wood laminate mat, the inner surface of the side guide is positioned outside the inner surface of the press machine side frame. When the laminated wooden body is inserted in this state, the side guide hits the end face of the molding die side frame, and the wooden material pieces stacked in the vicinity of the side guide are caught at the stepped portion or stuck in the gap, so that the wooden laminated mat is broken. This may cause the orientation of the laminated wooden material pieces to be disturbed and the insertion into the molding die not being possible.

  In the method of carrying a laminated wooden body on a call board etc. and transporting it with a conveyor while protecting both side surfaces with side guides, when the side guide in contact with both side surfaces of the wooden laminated mat is replaced, upstream or downstream If the side guide on the side is a movable side guide, for example, a side guide for a stockyard, there may be a positional shift between the upstream and downstream side guides due to the movement of the side guide. This causes a problem that the wood-based mat is caught on the side guide end, and the wood-laminated mat cannot be moved continuously while maintaining the orientation of the wood-laminated mat. Therefore, in such a clearance, there is a problem in that a continuous method for smoothing the flow of the wooden material pieces located on both side surfaces of the oriented laminated mat is required.

    The present invention replaces a wooden laminated mat oriented and stacked on a call board with another side guide for temporary storage in the middle of a conveyance line or in a stock yard without disturbing the stacked shape and orientation state, or press This was done for the purpose of providing a method of transferring onto the pressure plate surface of the molding apparatus.

  The side guide according to claim 1 is a wood laminate that conveys a wood laminate mat in which elongated wood pieces mixed with a binder are substantially aligned in the length direction by an orientation laminate device and conveyed from a transport laminate device to a press molding device. It is a side guide provided on the mat conveying device, and has elasticity that is bent on the inner side surface of the side guide so that the downstream end of the sheet does not protrude from the end of the side guide. A sheet is provided, and the folding portion is pushed and spread by the wooden laminated mat, and the sheet is returned to the original folded shape after passing through the wooden laminated mat.

  The transport device for the wood laminate mat according to claim 2, wherein the wood laminate mat obtained by stacking the long wood pieces mixed with the binder in the lengthwise direction with the orientation laminate device is stacked from the transport laminate device to the press molding device. A transport device for a wood laminate mat for transport, wherein a plurality of side guides according to claim 1 are connected in series on the transport device.

  According to a third aspect of the present invention, there is provided a transport method for a wooden laminate mat according to the second aspect, in which elongated wood pieces mixed with a binder are substantially aligned in the length direction and stacked with an orientation laminate device. When the wood laminate mat is supplied and the wood laminate mat passes through the connecting portion, the wood laminate mat passes the wood laminate mat through the connecting portion while the sheet is spread inside the side guide at the folded portion of the sheet. The sheet is returned to the original folded shape after passing through the wood laminate mat.

  In the present invention, the wood species of the wood lumber used mainly includes conifers such as cedar, cypress, spruce, fur, radiata pine, and broad-leaved trees such as birch, apiton, chamelere, Sengonlaut, and aspen. In addition to plant materials produced from the plant, plant materials produced outside the forest, such as bamboo and sorghum, can also be included.

  Forms that can be used as raw materials are not particularly limited, but include, for example, the above logs of logs, raw materials such as thinned wood, scraps generated at factories and residential construction sites, waste pallet materials discarded after transportation of components, and construction Examples include demolition waste materials generated during dismantling.

  The processing method to make the above-mentioned raw material wood pieces is a method of cutting a veneer processed with a rotary cutter into a chopsticks shape to make a stick, a method of cutting a log into a strand with a rotary blade of a flaker, a uniaxial crushing A method according to the situation, such as a method of crushing wood by rotating a roll with a cutter on the surface of the machine, can be used.

  And if the thickness of the timber pieces crushed as described above is uneven, it is classified into pieces of wood with a certain range of thickness as necessary. Although it will not specifically limit if it can classify | categorize with thickness, For example, the method of classifying using classifiers, such as a wave roller system, is mentioned. The wave roller type classifier is a device that classifies continuously based on the thickness of the wood pieces.

  In addition, the wood pieces obtained in this way are usually mixed with a binder by coating or the like before stacking. Examples of the binder include phenolic resin, urea resin, isocyanate, and the like sheets and particle boards. The adhesive for wood industry used for the above is mentioned, and these binders may be used alone or in combination of several kinds. The binder may be in liquid or powder form, but in the case of liquid, it is generally sprayed onto a wooden piece, or mixed with a wooden piece and mixed with the wooden piece in advance in the oriented lamination apparatus. In the case of a powder form, the powder is generally supplied to the orientation laminating apparatus in a state of being uniformly mixed with the wood piece. As the mixing device, a drum blender or the like is preferably used.

  Moreover, although the amount of the binder mixed depends on the density, shape, and surface state of the wood piece, it is usually preferably 1 to 20% by weight with respect to the weight of the wood piece. If it is less than this, the adhesion becomes insufficient, and if it is more than this, the adhesion performance is wasted, and the appearance and nailing performance of the obtained wood-based composite material may not be woody.

  Furthermore, it is preferable that the wood piece has a constant moisture content. By making the water content constant, the quality variation of the wood-based composite material during production is eliminated. A preferable water content is 0 to 30%. As a method for keeping the moisture content constant, for example, a method of leaving a piece of wood material for a certain period of time in a temperature-controlled oven can be mentioned.

  The wooden piece is of an elongated shape. That is, it is a piece of wood material in which the fiber direction of the tree is the same as the length direction, and the thickness, width, and length are not particularly limited, but from the viewpoint of suppressing variation in product physical properties, the thickness is about 1 to 15 mm Those are preferably used. In addition, the wood composite obtained from the wood laminate mat is preferably subjected to annealing treatment, cutting, and sanding processing in order to improve dimensional accuracy and surface properties after press molding.

  Note that aligning the wood pieces approximately in the length direction means imaging the surface state after stacking, measuring the angle between the long axis direction of the long wood pieces and the direction of the reference line, and calculating the average Calculate the value. The state of being oriented substantially in one direction means a state in which the average value of the angle formed by the direction of the reference line and the major axis direction of the wood material side is within a range of ± 30 degrees by this method.

  A conveyance apparatus says a belt conveyor, a chain conveyor, or a roller conveyor. The wood laminate mat in which the wood material pieces mixed with the binder are oriented and laminated is placed on a call board, and is transported to the press molding device via the stock yard by the transport device. In addition, a call board is a metal plate of a predetermined size such as stainless steel, iron, aluminum, etc., and a wooden material piece, that is, a wooden laminated mat, oriented and stacked thereon is placed and conveyed. .

  A pair of side guides that are in contact with both sides of the wood laminate mat is disposed above the call board. The wood pieces are oriented between the side guides and stacked in a mat shape to form a wood laminated mat, so that it is difficult to collapse in the direction perpendicular to the orientation direction, that is, the transverse direction of the wood laminated mat, but in its length direction. Tends to collapse. That is, the side guide has a function of preventing both sides of the wood laminate mat from collapsing during conveyance.

  Therefore, since the side guides only need to prevent both sides of the wood laminate mat from collapsing during movement, the pair of belt-like sheets of the side guides contacting both sides of the wood laminate mat may be general sheets. In particular, the material is not limited.

  The pair of side guides only need to be arranged so as to be in contact with both end surfaces of the wood laminate mat on the call board, and the support method is not particularly limited, but preferably a feed roller on which the call board is placed It is supported from the side of the supporting frame. As a side guide support method, for example, a side guide moving device such as an air cylinder, a hydraulic cylinder, or a motor provided with a side guide support is fixed to the housing of the transport device, and the side guide is fixed to the side guide support. Examples thereof include a method and a method of supporting the side guide by fixing the side guide support to the floor surface on which the conveying device is installed.

  Further, the upper end portions of the pair of side guides may be connected by a sheet or a rod so as to be bridged, and the shape seen from the front or the rear may be a tunnel-like shape. If it is a self-supporting shape, place it on a call board, cover the wood laminate mat, and use it with a pair of side guide sheets coming in contact with both sides of the wood laminate mat from above Can do. In any case, the collapse of both sides of the moving wooden laminate mat can be prevented.

  Moreover, since it is possible to transport the call board, the wood laminate mat, and the side guide as a single unit by using a side guide that can stand by itself, a stand-alone side guide is preferably used as the side guide for the stockyard. It is done.

  The lower side of the side guide and the upper surface of the call plate are not necessarily in a straight line state due to scratches during use, warpage due to the weight of the call plate itself, or the heat history of the press. Therefore, an elastic body such as rubber is provided at the lower end of the side guide, and when the side guide is moved, the elastic body is deformed so that the movement is smooth, or the surface of the call board or the like is not damaged. You may be allowed to.

  As for the distance between the pair of side guides, the distance in the direction of travel of the call plate may be narrower by about 1 mm to 5 mm, usually about 3 mm than the distance on the rear side. This is because when the transport distance is too long and a continuous side guide cannot be provided over the entire length of the transport path, the side guide is added to the side guide. This is because when replacing the side guide, both sides of the wooden laminated mat can be smoothly replaced without collapsing.

  The order and number of the side guides that are in contact with each other, such as the above-described support methods, are not particularly limited, and the free standing side guides may be arranged on the downstream side of the non-self supporting side guides, or vice versa. Further, the self-supporting side guides may be in line or the non-self-supporting side guides may be in line. Further, one or a plurality of side guides that are in contact with each other may be arranged side by side, and the wooden laminated mat may be conveyed to each side guide row as necessary. It may be conveyed to the next row.

  In the side guide of the present invention, the downstream side end of the sheet is bent inward of the side guide so that the inner side surface of the side guide, that is, the entire side where both side surfaces of the wood laminate mat are in contact, does not protrude from the side guide end. In addition, an elastic sheet is provided, and a folding portion is pushed and spread by the wooden laminated mat so that the sheet returns to the original folded shape after passing through the wooden laminated mat.

  A pair of side guides having a sheet on the inner surface is lined up, and the wooden laminated mat on the cole board held by the upstream side guide is conveyed into the downstream side guide, and the wood mat and the cole board are further downstream. When transported in the lateral direction, upward, or obliquely simultaneously with the side guide, the transported side guide and the upstream or downstream side guide move relatively sideways relative to the side guide. . In this case, since there is no wood laminated mat at the folding part, the seat is restored to the shape bent inward of the side guide so as not to protrude from the end of the side guide. Even if it moves so as to deviate, the sheet does not come into contact with the side guides, and therefore the orientation state and lamination state of the wood laminate mat are not disturbed.

  In addition, as described above, when the wooden laminated mat is moved, the sheet is pushed and spread on both sides of the moving wooden laminated mat at the bent portion, and the slope is applied to the step generated in the continuous portion. Both sides can move while sliding smoothly. Therefore, the wooden pieces that are oriented and laminated as a wood laminated mat are not stepped, the orientation is disturbed, the mat is not cracked, and the side guides that maintain the orientation are transferred to, for example, side guides in a stock yard. Is possible.

  As described above, the wood laminate mat placed on the call board is movable while one end of the sheet is bent inward at a substantially right angle. Therefore, for example, when temporarily storing a wooden laminated mat in the stock yard, the upstream side guide can be provided even if the call board carrying the wooden laminated mat moved to the stock yard is moved laterally in the stock yard. Since the extended portion of the seat does not protrude from the tip of the side guide, the seat provided on the upstream side guide does not contact the end of the stockyard side guide at the connecting portion. Similarly, when transferring a wooden laminated mat temporarily stored in a stock yard into a press die of a press molding device or when a side guide is replaced in the middle of a conveyance line, the sheet and The next side guide does not come into contact. Further, when the wood laminate mat is moved, the wood laminate mat is pushed and spread at the bent portion, so that the wood laminate mat slides smoothly on the inner surface side of the sheet, and the side guide can be replaced without changing the orientation state or the laminate state.

  The sheet is usually bent inward at a substantially right angle, but it can be maintained in a bent state at a substantially right angle, and the wooden laminated mat can be easily spread on both sides when passing, and many times. As long as it does not break even when bent and stretched, there is no particular limited material or bending method.

  For example, as an example, the sheet has a shape retention property at the bent portion, ease of spreading during transportation of the wood laminate mat, low friction between the film surface and the wood material pieces on both sides of the wood laminate mat, ease of handling, cost, etc. For example, as an example, thermoplastic resins such as polyethylene, polypropylene, vinyl chloride resin, polyamide, polyester resin, silicon resin, fluororesin; reinforced with fibers such as glass fiber and carbon fiber Thermosetting resins such as the above thermoplastic resins, polyester, polyurethane, etc .; metals such as iron, steel, aluminum, stainless steel, brass, bronze; surface of these materials subjected to wear resistance or low friction processing, etc. The sheet | seat or film which has elasticity, or a plate-like thing is mentioned.

  The thickness of the sheet should be such that the bent part of the sheet is not self-supporting and does not fall down, and may be appropriately selected depending on the material used for the sheet, but if it is too thick, the sheet will be spread by both sides of the wood laminate mat. Thus, when contacting the inner surface of the sheet provided on the next connected side guide, there is a possibility that a step is formed between the sheets at the contact portion, and the side surface of the moving wooden laminated mat may be disturbed. Therefore, the sheet thickness is preferably about 3 mm or less. For example, about 0.1 mm for a metal such as stainless steel, and about 0.2 mm for a polyethylene, polypropylene, fluororesin, fiber reinforced synthetic resin, etc., the thickness is sufficient.

  Although the sheet folding position is not particularly limited as long as it is upstream from the side guide end, it is usually provided at a position of 10 to 50 mm from the connecting portion, and when the side guide is moved, the folded sheet is the next side guide. Is set to a position where it does not come into contact.

  When the upstream side guide and the next side guide are displaced, the length of the bent portion needs to be longer than the displacement dimension. Therefore, it is usually preferable to be about 20 mm to 100 mm.

  The folding method of the sheet is such that the bent part continues to hold its bent shape, and is expanded only when the wooden laminated mat is in the bent part, and when the wooden laminated mat is lost, it is restored to the original bent shape. There is no particular limitation. For example, a V-shaped cut groove or the like is provided in a straight line at a position upstream of the side guide end on the side guide surface side of the sheet bent portion protruding from the side guide end, and inwardly according to the line. A method of folding a sheet and attaching a crease there, a method of attaching a crease in a state of being sandwiched between a side guide and a glass fiber sheet coated with a fluororesin provided on the inner surface thereof, a bent portion A method of attaching the adhesive tape made of a base material in which a fluororesin is laminated on a silicon cloth or a glass fiber cloth, for example, and connecting the sheet to the sheet provided on the inner side of the side guide. For example, a method of mechanically bending a sheet portion that is not bonded when the side guide is moved without attaching the portion to the side guide. .

  For example, as a specific example, the bent sheet may be provided in a state of being sandwiched between a glass fiber sheet coated with a fluorine resin provided on the inner surface of the upstream side guide. If it is provided on the surface of the sheet of the upstream side guide, there will be a step corresponding to the thickness of the sheet, and the wooden material pieces that are oriented and laminated will be caught by the step, causing the orientation state and lamination state to be disturbed Because it becomes.

  The sheet is provided on the inner surface of the side guide. Examples of the method include a method of sticking the sheet to the inner surface of the side guide with an adhesive or a pressure sensitive adhesive, and a method of hanging the sheet from the side guide to the inner surface side. When sticking, the tip position for adhesion or adhesion is set slightly inside the tip of the side guide. By doing so, when the side guides are continuously provided and the side guides are displaced from each other, the sheet becomes slanted, the step of the abutting part becomes gentle and the corners become smooth, so the wooden laminated mat can move smoothly It is.

  The transport device for a wood laminate mat of the present invention transports a wood laminate mat in which elongated wood pieces mixed with a binder are substantially aligned in the length direction by an orientation laminate device from the transport laminate device to a press molding device. A plurality of side guides described in the item 1 for controlling the ball are connected in series on the transport device.

  That is, in this transport device, the side guides described in Item 1 are connected in series in all the transport lines. For example, the wooden laminated mat is transposed in the middle of the transport line or in the stock yard, or the press molding device is molded. When the wood laminate mat is moved, such as when the wood laminate mat is transferred to a mold, the wood laminate mat can be moved without changing the orientation state or the laminate state of the wood laminate mat.

  According to a third aspect of the present invention, there is provided a transport method for a wooden laminate mat according to the second aspect, in which elongated wood pieces mixed with a binder are substantially aligned in the length direction and stacked with an orientation laminate device. When the wood laminate mat is supplied and the wood laminate mat passes through the connecting portion, the wood laminate mat passes the wood laminate mat through the connecting portion while the sheet is spread inside the side guide at the folded portion of the sheet. Thus, after the wood laminate mat passes, the sheet returns to its original folded shape.

  When the wooden laminated mat passes through the side guide continuous portion, the wooden laminated mat is passed through the continuous portion while the sheet is pushed and spread inside the next side guide at the bent portion of the sheet by the wooden laminated mat. After the wood laminate mat passes, the sheet returns to its original folded shape. That is, in this conveying method, since the side guide according to claim 1 is used, for example, when the wooden laminated mat is transferred to the middle of the line or the stockyard, or the wooden laminated mat is transferred to the molding die of the press molding apparatus. For example, when the wood laminate mat is moved, the sheet and the side guide are not in contact with each other, and the wood laminate mat can be moved without changing the orientation state or the laminate state of the wood laminate mat.

  Since the side guide of the invention has the above-described configuration, the sheet does not come into contact with the side guide when the transposition of the wooden laminated mat is finished and the side guide is moved. Therefore, the orientation state and the lamination state of the wood loading mat are not changed during the transshipment and the movement in the stock yard.

  Since the transport device of the present invention has the above-described configuration, the wood laminate mat is reloaded in the middle of the transport line or in the stock yard, or when the wood laminate mat is transferred to the molding die of the press molding device. When the wood laminate mat is moved, the transport device can move the wood laminate mat without changing the orientation state or the laminate state of the wood laminate mat.

  In the transport method according to the present invention, the wood mat is not changed in its orientation state and stacking state during transshipment and during movement in a stock yard, etc. Wood stacking without changing the orientation and stacking state of the wood laminate mat when moving the wood laminate mat, such as when transferring the wood laminate mat in the yard or when transferring the wood laminate mat to the mold of the press molding machine This is a transfer method that can move the mat.

  Next, the present invention will be described with reference to the drawings. 1A and 1B show an example of a state in which the side guides of the invention 1 are connected, wherein FIG. 1A is a side view and FIG. 1B is a plan view. FIG. 2 shows a state in which the wood laminate mat is moving, in which (a) is a side view and (b) is a plan view. FIG. 3 shows a state after the wood laminate mat is moved, (a) is a side view, and (b) is a plan view. FIG. 4 is a layout view of the conveying device of the present invention.

  An example of the transport device B is shown in FIG. It is an apparatus that conveys the call board (3) on which the wood laminate mat (M) is placed from the orientation laminating apparatus (H) to the press molding apparatus (P). Usually, a stock yard (S) for temporarily storing the wood laminate mat (M) is provided in the transport line in which the transport device (B) is arranged. The side guide of the present invention is used when it is necessary to replace the side guide in this conveying line, and the wooden laminated mat (M) is temporarily stored in the stockyard (S), or the press molding apparatus (P). It is particularly preferably applied to the case of transferring to a molding die or replacing the side guide in the transport line.

  The stainless steel side guides (11, 12) having a thickness of 2 mm are made of an epoxy-based sheet (21, 22) having a thickness of 0.35 mm, which is obtained by coating a glass fiber base material with a fluororesin. It is adhered and pasted with an adhesive. The lower ends of the sheets (21, 22) are extended downward so as to close the gap between the call plate (3) and the side guides (21, 22) placed on the conveying device B (the belt conveyor in this example). ing.

  Bent portions (41, 42) made of the same material as the sheets (21, 22) are provided at the downstream end of the sheets (21, 22) provided on the upstream side guides (11, 12). . The bent portions (41, 42) are located about 30 mm upstream from the end of the side guide, with one end of the sheet (21, 22) and the side guide (11, 12) made of stainless steel plate. It is fitted between and fixed with an epoxy adhesive or the like. Therefore, the sheet (21, 22) is slightly swelled and stepped at the fixed portion of the bent portions (41, 42), but the step is smooth and has a low step. Even if slidably moves, the orientation state and the lamination state do not change. The same applies to other side guides such as the following side guide.

  The length of the bent portions (41, 42) is about 20 mm to 100 mm, and is ½ or less of the width of the wood laminate mat M. The bent portions of the bent portions (41, 42) are the attachment portions of the sheet (2). The bent portion is processed so as to bend the glass fiber and maintain the bent shape by heating or the like.

  The side guides (11, 12) are connected to the next side guides (11 ′, 12 ′) to move the wooden laminated mat (M), and the side guides (11) where both side surfaces of the wooden laminated mat (M) are in contact with each other. , 12) is replaced with the next side guide (11 ′, 12 ′), the sheets (21, 22) are spread by the wood laminate mat (M). Therefore, the step which can be formed in the connecting portion (5) between the side guides (11, 12) and (11 ′, 12 ′) is smoothly blocked by the spread sheets (21, 22), and the wooden laminated mat ( The wood material piece oriented and laminated in M) does not spill from the gap, and the orientation state and the lamination state of the wood laminate mat (M) do not change.
